[Net7] ScrollView/Grid/Label width calculation broken on .Net 7, no issue on .Net 6

[MartinRothschink]

Description

Width of Grid inside a ScrollView is changed if label text changes. This did not happen with .Net 6.

.Net 7 behaviour after start

Click on Start button to change the text, the grid column widths change. Click on Stop to undo the change.

.Net 6 behaviour is fine

Steps to Reproduce

1. Create a new MAUI app
2. Replace MainPage.xaml with

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiApp1.MainPage">

    <ScrollView>
        <Grid ColumnDefinitions="2*, 1*, 3*" RowDefinitions="Auto,*" ColumnSpacing="4" RowSpacing="4">

            <Border Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="3" >
                <Grid ColumnDefinitions="72,72,*" ColumnSpacing="4" RowSpacing="4">
                    <Button Grid.Column="0" Text="Start" Pressed="ButtonStart_Pressed" />
                    <Button Grid.Column="1" Text="Stop"  Pressed="ButtonStop_Pressed"/>
                    <Label Grid.Column="2" x:Name="Label" Text="Short text" LineBreakMode="WordWrap" VerticalOptions="Center"/>
                </Grid>
            </Border>

            <Border Grid.Row="1" Grid.Column="0" Padding="24">
                <Rectangle BackgroundColor="Aqua"></Rectangle>
            </Border>

            <Border Grid.Row="1" Grid.Column="1" Padding="24">
                <Rectangle BackgroundColor="Aqua"></Rectangle>
            </Border>

            <Border Grid.Row="1" Grid.Column="2" Padding="24">
                <Rectangle BackgroundColor="Aqua"></Rectangle>
            </Border>
        </Grid>
    </ScrollView>
</ContentPage>

3. Replace MainPage.xaml.cs with

namespace MauiApp1;

public partial class MainPage : ContentPage
{
	public MainPage()
	{
		InitializeComponent();
	}

	private void ButtonStart_Pressed(object sender, EventArgs e)
	{
        	Label.Text = "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.";
	}

	private void ButtonStop_Pressed(object sender, EventArgs e)
	{
		Label.Text = "Short text";
	}
}

4. Run with .Net 7 and click Start/Stop
